Unusual spread of cervical adenocarcinoma to the endometrium and left fallopian tube: a case report and literature review.

ABSTRACT

Introduction: The incidence of cervical adenocarcinoma and adenocarcinoma in situ are gradually increasing especially in younger women. However, unusual spread of cervical adenocarcinoma has rarely been reported. Case presentation The authors report a case of a 60-year-old woman who presented with postmenopausal bleeding. She was misdiagnosed to have endometrial adenocarcinoma on the lower uterine segment depending on curettage specimen. After hysterectomy, it was revealed depending on morphological features in histology accompanied with immunohistochemistry that the patient had cervical adenocarcinoma with endometrial and left fallopian tube extension. Discussion: Distinguishing endocervical adenocarcinoma from endometroid adenocarcinoma poses many challenges especially when evaluating endometrial curettage specimens. Histological diagnosis based on morphological features combined with a panel of immunohistochemistry stains is crucial for accurate diagnosis and identifying the primary origin of the tumor. Conclusion: Accurate distinction between cervical adenocarcinoma versus endometrial adenocarcinoma is important because of its significant effects on choosing the appropriate treatment option.
